[SCSI] lpfc 8.3.15: FCoE Related Fixes
FCoE Related Fixes
- Correct find-next-FCF routine so that it searches at next FCF rather
than current one.
- Enhanced round-robin FCF failover algorithm to re-start on "New FCF"
async event
- Update the manner in which we look at FCFs while they may be in
their discovery state.
- Use LPFC_FCOE_NULL_VID macro when checkinf for valid vlan_id for FCF
